Abstract
A method for synchronizing an electronic interactive device on basis of a first sound track is provided. The method may include identifying a first peak point and a valley point of the first sound track by calculating a first energy of the first peak point and a first energy of the valley point of the first peak point and comparing the first energy of the first peak point with first energy of neighboring points of the first peak point. The method may also include identifying a first peak point of a second soundtrack, and determining a similarity between the first soundtrack and a second sound track on basis of the first peak point of the first soundtrack and the first peak point of the second sound track.
Claims18
A method for synchronizing an electronic interactive device on basis of a first sound track in terms of a time domain signal, comprising:
- identifying a first peak point and a valley point of the first soundtrack by calculating a first energy of the first peak point and a first energy of the valley point of the first peak point and comparing the first energy of the first peak point with first energy of neighboring points of the first peak point;
- identifying a first peak point of a second soundtrack;
- determining a signal-noise ratio (SNR) in connection with the first peak point to define a second peak point, wherein the number of the second peak points is no more than the number of the first peak points, and the second peak point is represented in terms of the frequency domain;
- and
- determining a similarity between the first soundtrack and the second sound track on basis of the first peak point of the first soundtrack and the first peak point of the second sound track;
- wherein the first peak point, the valley point, the neighboring points of the first soundtrack, and the first peak point of the second soundtrack are represented in terms of a frequency domain.
A non-transitory computer readable medium comprising a set of computer instructions capable of synchronizing an electronic interactive device on basis of a first soundtrack in terms of a time domain signal when executed by a processing unit of the electronic interactive device causing the processing unit of the electronic interactive device to:
- identify a first peak point and a valley point of the first sound track by calculating a first energy of the first peak point and a first energy of the valley point of the first peak point and compare the first energy of the first peak point with first energy of neighboring points of the first peak point;
- identify a first peak point of a second soundtrack;
- determine a signal-noise ratio (SNR) in connection with the first peak point to define a second peak point, wherein the number of the second peak points is no more than the number of the first peak points, and the second peak point is represented in terms of the frequency domain;
- and
- determine a similarity between the first soundtrack and the second sound track on basis of the first peak point of the first soundtrack and the first peak point of the second sound track;
- wherein the first peak point, the valley point, the neighboring points of the first soundtrack, and the first peak point of the second soundtrack are represented in terms of a frequency domain.
